Spots on My Chard: Not Sure I Like the Answer Why

Yesterday my chard looked like this, beautiful:

And now my chard looks like this, covered in brown spots, seemingly overnight ...

A quick search has uncovered the reason may be due to leaf miners. Which are disgusting. They are small grey flies, and they are "truly one of the grossest" garden pests, according to one writer. They literally lay eggs, which hatch, and the maggots burrow between the leaves of the plant.

Yes. Gross.

Getting Cool Weather Plants in the Ground: Lettuce, Kale and More!

I planted some cool-weather veggies last weekend - pre-Snowpocalypse here in Colorado. (For the third week straight it snowed, in April.  I'm ready for spring!)

I was so eager to get out there, and I wanted my lettuce to get a good start this year. I know that you can plant lettuce even earlier than I did, as it is a frost-hardy plant, but being a beginner, I'm pretty cautious.

I even expressed doubts about planting when I did; my husband responded by telling me to trust myself. I've read so much online and in books about gardening this year that I have too much information in my head, and it's making me think too hard about what's right and what's wrong. I didn't think at all last year, and things turned out OK. I think a new gardener needs to balance what they find in books with what they find with experience.
